在UF_CURVE_create_spline_thre_pts中有一项double parameters[ ] 说明中这样解释parameters of input points. This is a user specified
parameterization for the input points, which needs to be
monotonic increasing (i.e. parameters(i) < parameters(i+1)
for all i), but does not need to be normalized, if NULL
then the default parameterization will be used.其中这句if NULL then the default parameterization will be used我想应用这个NULL但又不知道怎么把它赋给parameters[],请求高手帮助.
